Cis-3-hexenol, also known as leaf alcohol, is a naturally occurring organic compound found in the essential oils of plants such as lemongrass, basil, and green leaves. It is a colorless liquid with a fresh, green, and leafy aroma. It is used in the fragrance industry as a top note in perfumes, colognes, and other scented products, and also used in the food and beverage industry as a flavoring agent. In perfumery, it is used to add a fresh, green, and leafy note to fragrances, particularly in floral and green scents. In food, it's used to flavor savory and sweet dishes, and in non-alcoholic and alcoholic beverages. It is considered safe for use in food and personal care products when used in appropriate concentrations, but it should be used with caution as high doses may be toxic.
